PALM is an open-source large-eddy atmospheric model developed jointly by Leibniz University of Han‑ over and other European academic institutions. The Institute of Computer Science is the main author of the urban surface energy balance model (USM) and the multi-reflection radiative transfer model (RTM) for PALM. The current PALM version (6.0) contains an overall upgrade of the RTM (version 3.0), which increases the scope of modelled processes and enables modelling of larger areas by utilizing new algorithms with improved efficiency and scalability and reduced computational complexity. During the development and testing of this new complex model, we needed to run multiple simulations to verify the correctness and convergent properties of the model using different scenarios, and to test the scalability and efficiency of the parallelization. This new version was described in the Geoscientific Model Development journal (GMD).
